How to disable the auto update dialog box shows every time while i am working? I have applied the following command yesterday but today still that is showing up. Is there any other way to permanently forever disable it?

In the update manager, click the settings button in the bottom right. In the Updates tab of the resulting window, there are a number of options that control the behaviour of the update manager.

What is annoying you is that the When there are security updates: setting is set to Display Immediately. If you would like the protection of these security updates without being bothered, consider setting this to Download and install automatically instead.

With this change, the update manager will pop up at most once a week for the non-security updates. You can switch this to fortnightly by changing When there are other updates: to Display every two weeks.

There is also an option to turn off checking for updates entirely in this tab, but I would recommend against picking it since it can leave your system vulnerable to preventable problems.

I also find this annoying as I use the command line to update my system on my netbook. One way to silence it is to remove the package:

apt-get remove update-manager-core

It will also remove ubuntu-desktop and the janitor packages but in my case (Gnome3) it makes no difference to the base system I'm using. I suspect you could also remove the notifier from the start-up applications but that requires making them visible to you in the first place.
